that was set and the environment was set up by the teachers. and so, in a sense, there was thoughtful planning put into what's going to be happening in the classroom, but at the same time, there's an openness about what the kids are interested in, what they're doing, that will allow you to focus in on their interests. at this point in time, i thought this was an interesting idea. so i started asking them some questions about what's going on, what they're doing, so as to get a sense of what they're thinking about initially so that we could talk about what the other teachers in the classroom-- where to go from this point. child: i'm seeing all of the colors. you're seeing all of the colors in the ocean. see that? i see there. where? show me again. where? i see green and red. you see green and red? me, too. do you see brown? no. hendrick: of course, no matter which techniques you decide to use, inevitably you will encounter some parents or family members who think you aren't doing enough fast enough, who want to accelerate the pace of their child's cognitive learning. woman: oh, let's see. let's
and plow the fields and harvest food. we have now created an environment so that this predisposion towards depositing fat in the body is no longer an advantage. it's a disadvantage. genes also play a role in how fat is distributed. the riskiest fat distribution is the male or android or apple shaped distribution where most of the fat is in the intra-abdominal cavity. there are many more metabolic consequences and many more medical problems associated with that fat distribution-- for example, high blood pressure, high cholesterol, diabetes mellitus. now that's opposed to the gynoid or female distribution, or pear distribution, where the excess weight is in the hips and the buttocks. now, for some reason, that obesity is much less likely toto contribute to the metaboc and health consequences. obesity is no longer confined to those who are middle aged or older. increasingly, the patterns associated with obesity are found in the very young. barbara korsch: many people believe a fat baby's a healthy baby, but from a health point of view, more obese babies go on to be fat adults. stopping the pr
. dolphins perceive most of their environment with the sense of sound. there's a way down there. it gets dark gang-- gets murky, doesn't it? and how does a dolphin get around? in fact, the dolphins kinda got us beat in a little way because a dolphin can communicate with others with the same sense that they receive information. we receive most of our information by sight, huh? now, how do you give that back to other people in terms of sight? we can't. so we've invented a language. we have letters of the alphabet. we have grammar. we have words. so someone can tell you, boy, did i have a neat time today. the physics that i saw was blah, blah, blah, blah, blah, blah, blah, yeah? and we have a language. and we've always wondered, how come that dolphins don't seem to have maybe like-- they don't an alphabet language, yeah? what's they're alphabet? how many letters, you know? what are they're word processors like? how do the dolphins do it? and there's some neat ideas on that. and the way the dolphins do it goes something like this-- it's speculated. what the dolphin does-- the dolphin swimming ove
the things in our environment here, aren't this, this, this, all these things the same temperature? what if this book were hotter? what would it do to the table? energy would cascade from the book to the table until they both became the same temperature and they will level off. so that alcohol that's poured on your back has the same temperature as anything else around, but it feels cold. and why does it feel cold, gang? because what is that alcohol doing? what it's doing is what we're gonna be talking about today. it's changing state. it's changing from the liquid state to the gaseous state, okay? and we call that what? begin with ev? evaporation. evaporation, that's right. and we're gonna be learning that evaporation is a cooling process. you know, sometimes you're swimming and you come out and you're all wet, a little breeze come by and you feel kinda chilly. but if no breeze comes by, you don't feel so chilly. and what's going on? when that breeze comes by, what happens to the water on your body? evaporates. it evaporates. when it evaporates, how does your body feel? begin with a c. -
